Image caption Scotrenewables' prototype tidal energy converter - the SR2000 - was involved in the first production of hydrogen. A Scottish test and research centre has claimed a world "first" by generating hydrogen gas from tidal energy. The European Marine Energy Centre (Emec) said it achieved the feat at its tidal energy test site in Orkney late last month. It added that it demonstrated the potential for a clean replacement for polluting fuels. Emec's investment in hydrogen production capability was backed by the Scottish government. Funding of £3m was made available through Highlands and Islands Enterprise. The hydrogen gas was produced after prototype tidal energy converters - Scotrene... Full story
